1 answer:
Rzqust [24]3 years ago
5 0

Answer:

I would believe that 5x - 12 = 3x + 30 should be the answer (simplify for x - literal equation).

Step-by-step explanation:

The bottom is a right angle, so both side angles are equal.

This shows that 5x - 12 = 3x + 30.

Solve for x.

a deep sea diver dives from the surface to 240 meters below the surface and then swims down another 25 meters,up 80 meters,up 12
Ne4ueva [31]

if your wanting to know how far the diver will be down you do 240+25 which is 265

265-80=185 (cause the diver swims up)

185+12+30 =227

227-16 =211

the deep see diver is at 211 meters below the surface

D. 10.83<br> Math question Please Help don't Guess
shepuryov [24]

Remark

You need to do some trig to get the final answer. There is no way around it. You can however, solve the first part with the Pythagorean Theorem.

Step One

Find AB

AB^2 = DB^2 + AD^2

AB^2 = 7.5^2 + 4.9^2

AB^2 = 56.25 + 24.01

AB^2 = 80.26

AB = sqrt(80.26)

AB = 8.9588

Step Two

Move to the triangle on your right. Find x

Tan(C)= opposite / adjacent

Tan(55.8) = AB/adjacent

Tan(55.8) = 8.9588/ x Multiply both sides by x

x * tan(55.8) = 8.9588 Divide by tan(55.8)

x = 8.9588/tan(55.8)

x = 6.09

Answer: A
